KEY MESSAGES

- Temperatures will remain below normal through the end of the week and into the weekend, with low-end precipitation chances for areas east of the Mississippi River.

- Cool nights in the low-mid 30s through the second half of the week may result in some frost, especially in our northern counties.

- Pattern change will bring a more active upper level pattern Sunday and beyond, resulting in increasing temperatures and chances for precipitation through the first half of the upcoming work week.

SHORT TERM /THROUGH TONIGHT/

Issued at 228 AM CDT Wed Apr 29 2026

The wave that brought cloud cover and light rain/drizzle through the area overnight pushes east this morning. As a result, we will see the remaining cloud cover scatter out rather quickly this morning, leaving us with more sun than clouds by afternoon. As clouds scatter out and we see some surface heating, we will start to see decent mixing to about 800 mb. Thus, we can expect breezy conditions today, with northwest gusts between 20-25 mph this afternoon. We will also mix down drier air, which should limit precipitation chances this afternoon as another weak disturbance passes through our northeast. If anyone has the chance to see light precipitation, it would be northwest Illinois. Temperatures today will be similar to yesterday, with our north in the upper 50s and south in the low 60s. When combined with the afternoon breeze, the air might have a little chill to it. As the sun sets, we will see winds drop off quickly, along with temperatures. We will see temperatures drop into the upper 30s tonight, owing to mostly clear skies and light winds.

LONG TERM /THURSDAY THROUGH TUESDAY/

Issued at 228 AM CDT Wed Apr 29 2026

Broad trof and cutoff upper low over the Great Lakes Region will remain in place through the start of the weekend. Within this pattern, we will see bouts of energy gyrate around the upper low, which will bring through bouts of cloud cover and low-end chances for precipitation. LLVL flow will remain light and generally out of the north/northwest, keeping us under cool/dry advection. Thus, we will be fighting for moisture as these pass through. Although, there remains a chance for drizzle to light rain each afternoon through the end of the week. Best chances will be for areas east of the Mississippi River, with chances still <20%. QPF will remain <0.10" for the next three days. Overall, much of the area should remain dry through this timeframe. Temperatures will remain below normal through the end of the week, with upper 50s in the north to low 60s south. With each bout of vorticity passing along the flow, we can expect a cool northwesterly breeze, making it feel a little cooler. Nighttime temperatures will be in the low-mid 30s. Thus, there will be chances for frost in our northern half of the forecast area Thursday night and Friday night.

Sunday and into the start of the new work week, we will see stronger northwest flow work into the north-central CONUS. This will usher in stronger waves, which will start to shift the aforementioned upper low east. Better llvl return flow will work into the region, resulting in increasing tempertatures. Much of the area will start to see the upper 60s to low 70s return. Moisture will also be on the gradual increase through the start of the week, with the upper level pattern becoming a little more active. Thus, we will see sporadic chances for precipitation (20-40% PoPs each day) through the first half of the week. These seem to be quick-hitting systems, largely bringing through bouts of light rain.

AVIATION /06Z TAFS THROUGH 06Z THURSDAY/

Issued at 1210 AM CDT Wed Apr 29 2026

VFR conditions will prevail through the TAF period, with a broken-overcast deck of clouds around 8000 ft. These clouds will remain through the night, scattering out through the morning. Otherwise, we will start with northwest winds around 10 KTs, increasing after 15z throughout. Gusts upwards to 25 KTs out of the northwest can be expected through through Wednesday, prior to winds dying down around 00z Thursday.
